DETAILED DESCRIPTION

[0034] The placement and storage requirements of items in the car body is one of the important indicators to measure the ride comfort of the vehicle. With the development of intelligent vehicle design, vehicles play an increasingly important role in people's daily lives, and more and more items need to be stored in the car body. At present, the car body only has storage space in the glove box position, which is difficult to meet user requirements and is cumbersome to take and put. The size of the storage space and the convenience of taking and putting items will directly affect the customer's car experience, so the structural setting in the corresponding direction is crucial.

[0035] In order to make the technical personnel in this field better understand the present invention, the embodiments of the present invention are described below with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary for the solutions of the utility model described in the claims.

[0036] See also Figure 1-11The lifting mechanism provided by the embodiment of the utility model specifically includes a base 10, a driving unit 20, a transmission rod 30, a first support frame 410 and a second support frame 420, so as to drive the bottoms of the two support frames in the vertical direction to drive the positions of the tops of the two support frames to change, and realize the position change of the target object. Specifically, see Figure 2 and Figure 3 The driving part 20 is connected to the transmission rod 30 in a transmission connection so as to drive the transmission rod 30 to move in a horizontal direction when started. The driving part 20 drives the transmission rod 30 at least including pushing out and pulling back actions, that is, realizing the forward and reverse movement of the transmission rod 30 in the horizontal direction. The driving part 20 serves as a power source of the lifting mechanism and inputs power to the two support frames through the transmission rod 30.

[0037] The first support frame 410 and the second support frame 420 are cross-arranged, and the connecting pin 920 shaft 430 is penetrated at the intersection of the two, so that the first support frame 410 and the second support frame 420 are hingedly connected. It should be noted that the cross-arrangement of the first support frame 410 and the second support frame 420 specifically refers to that on one side of the intersection, the end of the first support frame 410 is higher in the vertical direction than the end of the second support frame 420, and on the other side of the intersection, the end of the first support frame 410 is lower in the vertical direction than the end of the second support frame 420. The height of the end of the second support frame 420 in the vertical direction; on the basis of the above structure, the first support frame 410 is hinged to the transmission rod 30 at the first end in its length direction, and the second end of the first support frame 410 is hinged to the target object. Preferably, the second end of the first support frame 410 is connected to the bottom end of the target object to drive the target object through the jacking action. Compared with the method of lifting on both sides or pulling on the top, its structure is more compact and easy to set up. In addition, during the driving process, the gravity direction of the target object is supported, making the movement process of the target object more stable.

[0038] The first end of the second support frame 420 is hinged on the base 10, and the base 10 is a fixed structure to carry the drive unit 20 and other component structures. The first end of the second support frame 420 is hinged on the base 10 to provide a constant rotation center for the movement process of the second support frame 420, and the second end of the second support frame 420 is relatively slidable in the horizontal direction with the target object.

[0039] The first end of the first support frame 410 and the first end of the second support frame 420 are both located below the intersection of the two, so that when the first end of the first support frame 410 is driven by the transmission rod 30, it can drive the second support frame 420 to rotate, and preferably, the first end of the first support frame 410 and the first end of the second support frame 420 are set at the same horizontal height, and the end height does not change during the rotation of the two support frames, thereby achieving stable support for the upper end.

[0040] In the above structure, see Figure 1 and Figure 4 The lifting mechanism drives the target object in the vertical direction specifically as follows: during the lifting process, the driving unit 20 starts and drives the transmission rod 30 to move in the horizontal direction, the first support frame 410 hinged on the transmission rod 30 is driven to rotate, and the first end of the first support frame 410 will move in the horizontal direction toward the first end of the second support frame 420. When the first end of the second support frame 420 is fixed, the first end of the first support frame 410 and the first end of the second support frame 420 approach each other, which will cause the intersection of the first support frame 410 and the second support frame 420 to rise in the vertical direction; at this time, the first support frame 410 rotates, and the second end of the second support frame 420 is a structure rotatably connected to the target object, so the second end of the second support frame 420 and the second end of the first support frame 410 will also move close to each other, so that the structure of the cross-arranged first support frame 410 and the second support frame 420 is erected, that is, the cross-arranged structure is formed. In the triangle formed by the intersection point and the endpoints on the same side of the first support frame 410 and the second support frame 420, the internal angle with the intersection point as the vertex position becomes smaller, and the target object supported by the second end of the second support frame 420 and the second end of the first support frame 410 will be lifted in the vertical direction to complete the lifting; it should be noted that when the target object needs to be lowered, it is only necessary to drive the transmission rod 30 to move in the horizontal direction through the driving unit 20 to drive the first end of the first support frame 410 to move away from the first end of the second support frame 420 in the horizontal direction, so that the internal angle with the intersection point as the vertex position in the triangle formed by the intersection point and the endpoints on the same side of the first support frame 410 and the second support frame 420 can be increased, so that the structure of the cross-arranged first support frame 410 and the second support frame 420 shrinks and collapses, thereby driving the target object to descend.

[0041] The lifting mechanism provided by the embodiment of the utility model drives the transmission rod 30 to move in the horizontal direction through the driving part 20, so as to serve as the power input of the first support frame 410 and the second support frame 420. At the same time, the first support frame 410 and the second support frame 420 are designed as a cross structure and are hinged at the intersection position through the connecting pin 920 shaft 430, so that the first support rod and the second support rod can form two triangular structures, namely, a triangle with the intersection, the first end of the first support frame 410, and the first end of the second support frame 420 as vertices, and a triangle with the intersection, the second end of the first support frame 410, and the second end of the second support frame 420 as vertices, and the first end of the first support rod is hinged on the transmission rod 30, so that The first end of the second support frame 420 is driven by the transmission rod 30 to move closer to or away from the fixed position and change the shapes of the two triangular structures. When the inner angle of the vertex at the intersection position changes from large to small, the inner angle becomes sharper and the first support frame 410 and the second support frame 420 are lifted in the vertical direction as a whole to increase the height of the target object; when the inner angle of the vertex at the intersection position changes from small to large, the inner angle becomes gentler and the first support frame 410 and the second support frame 420 are retracted in the vertical direction as a whole to lower the height of the target object. At the same time, the second end of the first support frame 410 and the second end of the second support frame 420 are connected to the bottom surface of the target object at intervals to drive the target object from two positions to improve the stability of the target object lifting process.

[0042] It should be noted that, with the help of the above-mentioned lifting mechanism, the target object is designed as a storage structure and is arranged in close proximity to the body structure. When the storage structure is not needed, the storage structure can be retracted through the lifting mechanism without affecting the aesthetics of the body, and when the storage structure is needed, the storage structure can be pushed out through the lifting mechanism for passengers to use. The above-mentioned embodiment is explained by taking the lifting of the lifting mechanism in the vertical direction and driving the movement of the storage structure in the vertical direction as an example. Of course, the lifting mechanism can also be arranged horizontally to realize the pushing out and retraction of the storage structure in the horizontal direction. It is arranged according to the application conditions, that is, the position of the cavity on the body suitable for setting the storage structure. The arrangement of the lifting mechanism at different positions will not be repeated here.

[0043] In order to ensure the transmission effect between the first support frame 410 and the second support frame 420, and between the first support frame 410 and the second support frame 420, see Figure 2 and Figure 4In some embodiments of the present invention, the first support frame 410 is a rod-shaped structure, and the second support frame 420 is a regular frame structure. It should be noted that the regular frame structure of the second support frame 420 here specifically refers to the second support frame 420 having an axially symmetrical rectangular or square structure to achieve stable force transmission, and the first support frame 410 is arranged on the bisector plane of the second support frame 420 in the vertical direction, so that when the second support frame 420 is lifted or pulled back by the connecting pin 920 shaft 430, the force on both sides of the second support frame 420 is more uniform, and in the first At the intersection of a support frame 410 and a second support frame 420, the first support frame 410 is also provided with an integral shaft sleeve protruding outward to abut against the inner wall surfaces of the second support frames 420 on both sides, thereby avoiding the risk of the first support frame 410 shaking left and right relative to the second support frame 420 during transmission; and in some embodiments of the utility model, in order to avoid interference between components, the first end position of the second support frame 420 is designed as an open structure, that is, the second support frame 420 is a U-shaped structure as a whole, so as to avoid the driving part 20 and the transmission rod 30 during the operation and avoid the risk of collision.

[0044] It should be noted that in the above structure, any hinged position, such as the first end of the first support frame 410 and the transmission rod 30, the first support frame 410 and the second support frame 420, the first end of the second support frame 420 and the base 10, etc., can be provided with a bushing and a gasket with an anisotropic ring structure to reduce the risk of loosening of the hinged structure.

[0045] The driving unit 20 inputs power to the first end of the first support frame 410 through the transmission rod 30. The stability of its power input is crucial to the subsequent stable movement of the first support frame 410 and the second support frame 420. Therefore, in some embodiments of the utility model, the transmission rod 30 is a horizontally arranged screw structure, and the driving unit 20 and the screw are connected through a worm gear and a worm to form a horizontal screw lifting mechanism. Specifically, the driving unit 20 only needs to drive the worm to achieve a simple rotation action. The corresponding driving unit 20 can adopt simple power source components such as cylinders and motors, and the worm is meshed with the outer periphery of the worm wheel to drive the worm wheel to rotate in a circular direction when rotating. At the same time, the center of the worm wheel is opened and provided with an internal thread, and the screw is It is arranged to pass through the center hole of the worm wheel and to mesh with the center hole of the worm wheel so as to drive the screw to move while the worm wheel rotates. The above-mentioned transmission structure adjusts the direction of the driving force by arranging a worm wheel and a worm in combination with the screw, so that the driving part 20 can realize the movement of the transmission rod 30 in its own axial direction through simple rotation drive, and the transmission rod 30 that only moves in the axial direction only needs to be simply connected to the first end of the first support frame 410 through a pin shaft to realize the driving of the first support frame 410; it should be noted that the conversion of the driving force, that is, the conversion from rotation to the axial movement of the transmission rod 30 can be achieved through the cooperation of the worm wheel and the screw, or through the cooperation of the bevel gear and the screw, and the setting structure is similar, which will not be repeated in this article.

[0046] In order to reduce the complexity and cost of the lifting mechanism, in some embodiments of the utility model, the driving part 20 is a motor, and in order to avoid vibration during the motor driving process and affect the driving stability of the lifting mechanism on the target object, the motor is also provided with a motor bracket 210, and the motor bracket 210 is composed of a plurality of U-shaped parts with openings facing each other. The closed end of the U-shaped part locks the motor at the bottom, and the open end is fixedly connected to the base 10 by screws to prevent the motor itself from vibrating relative to the base 10.

[0047] Furthermore, in the lifting mechanism provided in the embodiment of the utility model, the base 10 is a cavity structure enclosing the first support frame 410 and the second support frame 420, and a guide groove 110 is opened on the side wall of the base 10, and the guide groove 110 is arranged along the vertical direction for the limiting protrusion on the target object to be embedded and inserted, so that the target object can be lifted and lowered in the vertical direction.

[0048] It should be noted that the above embodiment is only a guiding method for driving a target object that needs to be lifted in the vertical direction. When the target object needs to be lifted obliquely, the guide groove 110 can also be tilted to meet the lifting and guiding requirements of the target object.

[0049] Further, see Figure 5In some embodiments of the utility model, a storage box is also provided, which storage box at least includes a box body 50, a drawer 60 and a lifting mechanism provided in any of the above embodiments. The drawer 60 is slidably connected to the box body 50 to switch between a closed state and an open state, and the lifting mechanism is used to drive the box body 50 to lift and lower. A slide groove 520 is provided on one side of the box body 50 connected to the lifting mechanism, and a pin is passed through the second end of the second support frame 420. The slide grooves 520 are preferably arranged in parallel, and the two slide grooves 520 are respectively located on both sides of the second support frame 420, and the two ends of the pin are arranged through the sliding grooves, so that when the first end of the first support frame 410 is driven by the driving unit 20, the second end of the second support frame 420 slides in the slide groove 520 to realize the shape change of the first support frame 410 and the second support frame 420, and realize the lifting and lowering of the box body 50.

[0050] Based on the above structure, the drawer 60 in the storage box for storing items is not limited to being installed openly in the vehicle body, but can be set in other areas of the vehicle body with hidden cavities, and the box body 50 and the drawer 60 can be pushed out of the hidden cavity by the driving of the lifting mechanism to provide space for passengers to store items. When not in use, the box body 50 and the drawer 60 can be retracted into the hidden cavity by the lifting mechanism to maintain the aesthetics of the vehicle body.

[0051] As for the arrangement of the drawer 60 in the box body 50, see Figure 5 and Figure 6 In some embodiments of the utility model, a receiving cavity 510 is provided on the box body 50, and the drawer 60 is slidably arranged in the receiving cavity 510. The lifting mechanism changes the height of the box body 50 in the vertical direction through the action of the driving unit 20, and drives the receiving cavity 510 to move. When it is necessary to pull out the drawer 60, it is only necessary to drive the receiving cavity 510 to a position where the hidden cavity is exposed, and then the drawer 60 can be pulled out to store items.

[0052] In some other embodiments of the utility model, in order to not only meet the needs of passengers on one side of the drawer 60 for taking and placing items, on the basis that the accommodating chamber 510 can be raised and lowered in the vertical direction, the drawer 60 is slidably arranged in the accommodating chamber 510 and can be pulled out or pushed back into the accommodating chamber 510 along the first direction, so as to realize the functions of opening and placing items and closing the drawer 60, and the accommodating chamber 510 is a structure with openings at both ends in the first direction, so that the drawer 60 can be pulled out from either side of the accommodating chamber 510 in the first direction. After the storage box is set, users located on opposite sides of the accommodating chamber 510 in the first direction can open the drawer 60 to store items. By adjusting the setting position of the accommodating chamber 510, the purpose of having users in the front and rear rows, or on the left and right sides of a single row share one drawer 60 can be achieved.

[0053] Specific to the movement process of the drawer 60, the movement path of the drawer 60 in the first direction will at least pass through the first position, the second position and the third position, wherein the drawer 60 is completely embedded in the accommodating cavity 510 when it is in the first position, and the top opening of the drawer 60 is completely blocked by the upper wall of the accommodating cavity 510, so that the drawer 60 is in a closed storage state; and when the drawer 60 is in the second position and the third position, it slides out of at least part of the drawer 60 space from the accommodating cavity 510, so that the top opening of the drawer 60 is at least partially offset from the upper wall of the accommodating cavity 510, and the drawer 60 is in an open state for taking and placing items, and when the drawer 60 is in the second position and the third position, it is pulled out in reverse from the two openings of the accommodating cavity 510 in the first direction respectively; it should be noted here that the drawer 60 can slide out of the accommodating cavity 510 in a partial area for taking and placing items, or a slide rail can be set to make the entire area of ​​the drawer 60 slide out of the accommodating cavity 510 and meet the passengers' needs for taking and placing items with a large opening.

[0054] In order to ensure that the drawer 60 remains stable in various positions during movement to meet the needs of passengers, the embodiment of the utility model provides a limit assembly for locking the position of the drawer 60. Specifically, when the drawer 60 is located at the first position, the second position or the third position, the limit assembly locks the drawer 60 and the box body 50. The purpose of limiting the drawer 60 to the first position is to lock the drawer 60 in the storage state to prevent the drawer 60 from sliding out abnormally. Correspondingly, the purpose of limiting the drawer 60 to the second position or the third position is to keep the drawer 60 in a stable open state when the user takes and puts items.

[0055] In the storage box provided in the embodiment of the utility model, the limit component can be a magnetic structure or a mechanical clamping structure. The limit component is explained as a magnetic structure. A plurality of first magnets can be embedded at intervals on the side wall where the drawer 60 contacts the accommodating cavity 510, and a plurality of second magnets are embedded at intervals on the inner wall of the accommodating cavity 510. When the drawer 60 slides to the first position, the second position or the third position, at least one first magnet is attracted and connected with one second magnet, and the attraction force of a single group of the first magnet and the second magnet is greater than the force of the drawer 60 moving on either side of the first direction under its own weight and being driven by the vehicle body, so as to achieve the locking of the drawer 60. When unlocking is required, the user only needs to push or pull the drawer 60 to overcome the attraction force of the first magnet and the second magnet to complete the subsequent movement of the drawer 60.

[0056] In some embodiments of the utility model, the limiting assembly is a mechanical clip structure. Specifically, the limiting assembly includes a follower plate 70 and a limiting ball 80. A mounting groove 610 is opened on the side wall of the drawer 60 in contact with the accommodating cavity 510. The follower plate 70 is embedded in the mounting groove 610 to move synchronously with the movement of the drawer 60, and the limiting ball 80 is fixedly set on the inner wall of the accommodating cavity 510.

[0057] It should be noted that the limiting ball 80 is a structural member with a ball head at one end and a rod-shaped structure at the other end, so that it is fixedly arranged on the accommodating cavity 510 through the rod-shaped structure, and the limiting action is realized through the structure of the ball head. Figure 7 The following piece 70 is provided with at least a first limiting hole 710 and a second limiting hole 720 at intervals in the first direction, and a plurality of limiting balls 80 are provided on the side wall of the accommodating cavity 510. On this basis, when the drawer 60 moves to the second position, the limiting ball 80 is inserted into the first limiting hole 710 to lock the following piece 70 and the drawer 60. When the drawer 60 moves to the third position, the limiting ball 80 is inserted into the second limiting hole 720 to lock the following piece 70 and the drawer 60. Furthermore, when the drawer 60 is in the first position, the first limiting hole 710 is inserted into the limiting ball 80 to lock the following piece 70 and the drawer 60. A limiting ball 80 is inserted into the inner part of the positioning hole 710 and at least one of the second limiting holes 720 to lock the drawer 60 in the first position. The above structure, combined with the movement law of the drawer 60, can limit the drawer 60 in three positions in the first direction only through two limiting holes. At the same time, the limiting ball 80 with a ball head structure at one end is a guiding structure in all directions during the process of inserting into and leaving the limiting hole. The process of the user driving the drawer 60 to leave the limiting hole is smoother due to the effect of the arc-shaped guide, thereby improving the smoothness of the push and pull process of the drawer 60.

[0058] It should also be noted that the first limiting hole 710 and the second limiting hole 720 are provided on the follower plate 70 in order to meet the limitation of the three positions of the drawer 60 while reducing the complexity of the components, and more limiting hole structures can also be provided on the follower plate 70 to cooperate with the limiting ball 80, which will not be repeated here.

[0059] In order to further improve the safety of the drawer 60, the drawer 60 is ensured to be stable during the pulling process and in the pulled state. Figure 9-11In some embodiments of the present invention, the limit assembly also includes a limit pin 90, which specifically includes an end head 910, a connecting shaft and a stop plate 930 with an integrated structure, wherein the connecting shaft is located in the middle position and fixedly connects the end head 910 and the stop plate 930, and correspondingly, a limit groove 5110 is provided on the top of the accommodating cavity 510, and the connecting pin 920 is arranged through the limit groove 5110, that is, the connecting shaft passes through the limit groove 5110, and the end head 910 and the stop plate 930 are respectively arranged inside and outside the accommodating cavity 510, specifically, the stop plate 930 is arranged inside the accommodating cavity 510; the structure of the stop plate 930 is designed to be a plate-like structure with a larger area, and the drawer 60 will abut against the stop plate 930 through its inner wall during the sliding process, thereby driving the stop plate 930 to move The connecting shaft moves, and the connecting pin 920 slides along the limiting groove 5110. When the drawer 60 is in the second position, the connecting shaft moves to one end position of the limiting groove 5110, and the connecting pin 920 cannot continue to move, and the stop plate 930 prevents the drawer 60 from further moving, so that the drawer 60 is stably located in the second position; correspondingly, when the drawer 60 is in the third position, the connecting shaft moves to the other end position of the limiting groove 5110, and the stop plate 930 limits the drawer 60, so that the drawer 60 is stably located in the third position; it should be noted that the setting of the limiting pin 90 and the limiting groove 5110 is only to limit the drawer 60 in the second position and the third position, and cooperate with the follower plate 70 and the limiting ball 80 to achieve the stability of the open state of the drawer 60.

[0060] It should be further explained that the accommodating cavity 510 preferably has two limiting grooves 5110 symmetrically arranged on its upper wall surface, and at the same time a limiting pin 90 is passed through each limiting groove 5110, so that when the limiting pin 90 applies a limiting effect to the drawer 60, the resistance is uniform, thereby avoiding the drawer 60 from being skewed.

[0061] On the basis of the structure of the above-mentioned embodiment, in order to prevent the limit pin 90 from moving disorderly and generating noise or shaking when the drawer 60 abuts against and drives the limit pin 90 to move, the inner and outer wall surfaces of the top of the accommodating cavity 510 are both provided with a groove along the first direction, and the length of the connecting shaft is designed so that when the connecting shaft passes through the groove, the end head 910 and the stop plate 930 on both sides of the connecting shaft are in contact with the upper and lower sides of the accommodating cavity 510 respectively, and correspondingly, the side where the end head 910 and the stop plate 930 contact the top of the accommodating cavity 510 is respectively provided with The raised portion 940 is embedded in the groove body to guide the movement of the limit pin 90, and at the same time, the limit pin 90 can only move in the groove body direction of the groove body, and cannot move obliquely. At this time, the posture of the stop plate 930 is set to be parallel to the side wall of the drawer 60 in the first direction, so that when the drawer 60 contacts the stop plate 930 and the drawer 60 and the limit pin 90 move synchronously, the parallel fitting state of the side wall of the drawer 60 and the stop plate 930 can be maintained, thereby improving the stability of the drawer 60 operation process.
